Please check notes in each part listing to ensure the Oil Pump is correct for your 1977 OLDSMOBILE OMEGA F85 with a 5.0L 305 2BBL OHV engine. Special restrictions like "California only" or "with sport package" may indicate a Oil Pump fits only certain 1977 OLDSMOBILE OMEGA F85 models.

Clicking a "More Info" link will display a picture and/or other details about that Oil Pump in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Oil Pump, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button, or click on "Find More Parts", to find more Engine parts, other OLDSMOBILE OMEGA F85 parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching. Both catalogs use the same shopping cart, so any auto parts you've already chosen for your 1977 OLDSMOBILE will not be lost if you switch.
